SCREEN.

To all whom it may concern:

Be ;it known that I, Earn. J. WHITE, a citizen of the United btates, residing in the county'of Brown, State of WVisconsin, near Pulaski, county of Shawano, and State of Wisconsin, have invented certain new and useful Im rovements in Screens, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to window screens and has for its primary object the provision of a screen of this character which may be interposed at a point between the sashes and located with such relation to the sill that it may be readily connected with the lower sash and in such manner as to follow the sash in its movements.

Another object of the invention is the provision of a casing for supporting the screen fabric in a manner which will permit the edges of the fabric to freely slide against the adjacent parting strips and at the same time confine such edges against the parting strips so as to prevent insects from passing between the screen and the sides of the frame.

Another object of the invention is the provision of a screen structure of this character mounted upon a spring tensioned roller whereby under the normal action of the spring the fabric will be maintained in a wound condition while being free to move to an active extended position, on movement of the sash to an opened position.

Figure 1 is a perspective view showing the application of the screen to an ordinary window structure, the lower sash being shown in a partly opened position. Fig. 2 is a "ertical section therethrough. Fig. 3 is a perspective view of the roller supporting casing. Fig. 4 is a detail sectional view of the roller.

I contemplate providing a window screen which may be mounted upon a spring tensioned roller and disposed immediately above the sill of an ordinary window structure and connected with the lower sash so that when the latter is moved to one position or another, the screen will be made to .follow the same and when the sash is opened the screen will be actively extended over the opening made by the opening of the sash.

I also desire to so construct the screen generally that the edges of the fabric will be free to move against the adjacent parting strips while being confined thereagainst in Specification of Letters Patent.

such manner as will positively prevent ins being free, as at 6, from the adjacent upper edges of the ends 4, and as illustrated, the sand top wall 5 is extended to a point slightly beyond the ends 4 where it will be free to bear against the screen fabric in a manner to be hereinafter fully explained. The free edge of the wall 5 is curved longitudinally, as at 7. The wall 2 is provided at requlred intervals with passages 8 for the reception of fastenings that may be driven into the sill A of the window frame B, while the ends 4 are provided with one or more passages 9 that are likewise adapted to receive fastenings so that the ends may be properly confined against the adjacent sides of the frame.

The ends 44 are up-struck or formed to provide substantial boss-like portions 10 and as illustrated, these bosses are provided with central apertures 11 which are designed to receive the mating ends 12 of a spring tensioned roller 13. This roller is co-extensive with the casing 1 and as shown. the fixed pintle of the roller is connected in the usual manner by a spring 14 so that the latter will serve to revolvethe roller in one direction. The roller is provided with a continuous, groove 15 in which one edge of the flexible screen fabric 16 is confined. The arrangement of the casing generally is such that it is provided with an open side located directly opposite the lower horizontal bar of the lower sash C. Secured to the said lower bar of the sash C is a strip 16. This strip has a thickness equal to the thickness of the parting strips E. Through the arrangement of the parts just specified, it is obviously apparent that the free edge of the screen fabric may be drawn through the open side of the casing 1 and then secured throughout the length of the strip 16. The free edge of the wall 5 of the casing 1 will be free to 'bear against the screen fabric and as a consequence thereof the vertical edges of the fabric will be confined positively against the parting strips so that the spaces between the fabric and Patented Nov. 24,1914;

held against passing between the strips and the fabric Through the fact that the roller is constantly under the tension of the mentioned spring, it is obvious that as the lower sash is moved in a downward direction, the fabric will be rewound upon the roller, while when the sash is opened, the fabric will move against the action of said spring and it will be operatively extended over the opening made by the opening of the sash.

What I claim, is:

In a window screen structure, the combination with a casingopen at one side and provided with terminal securing Walls adapted to be secured to the vertical edges of the window frame and provided with roller bearings, the lower wall of the casing constituting a securing member, a yieldable screen engaging wall being arranged at an incline and having its free longitudinal edge curved outwardly, a roller mounted in the bearings and free to revolve therein, and a continuous sheet of wire fabric arranged upon the roller having its free end secured to the lower sash to be raised and lowered therewith.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
